【Abstract】 Wielandts lemma is of most useful in estimating and finding characteristic values of matrices. This paper concentrates on generalized eigenvalue problem Ax=λBx where A and B are special matrices in economic analysis. Using the method somewhat similar to one in the proof of Wielandts lemma, we prove a more complicated Wielandt theorem on generalized eigenvalues.更多还原
